Prior to this change, it would mark only the first layer of
child transactions abandoned, due to always following the input hashTx
rather than the current now tx.
I thought we had removed this a long time ago, TBH, its really
confusing feedback to users that we display whether a tx was
broadcast to immediate neighbor nodes, given that has little
indication of whether the tx propagated very far.
Makes AddAndGetDestinationForScript use a generic CKeyStore rather than
the wallet, and makes it always add the script to the keystore, rather
than only adding related (redeem) scripts.

This improves the handling of INVALID in IsMine:
* Extra INVALID conditions were added to `IsMine` (following https://github.com/bitcoin/bitcoin/pull/13142/files#r185349057), but these were untested. Add unit tests for them.
* In https://github.com/bitcoin/bitcoin/pull/13142#issuecomment-386396975 it was suggested to merge `isInvalid` into the return status. This PR takes a different approach, and removes the `isInvalid` entirely. It was only ever used inside tests, as normal users of IsMine don't care about the reason for non-mine-ness, only whether it is or not. As the unit tests are extensive enough, it seems sufficient to have a black box text (with tests for both compressed and uncompressed keys).
Some addition code simplification is done as well.

Instead of combining the -limitancestorcount and -limitdescendantcount into a nMaxChainLength, this commit uses each one separately in the coin eligibility filters.
TransactionWithinChainLimits would take a 'limit' and check it against ascendants and descendants. This is changed to take an explicit
max ancestors and max descendants value, and to test the corresponding value against its corresponding max.

Pull request description:
Our current `IsMine` logic does several things with outputs:
* Determine "spendability" (roughly corresponding to "could we sign for this")
* Determine "watching" (is this an output directly or indirectly a watched script)
* Determine invalidity (is this output definitely not legally spendable, detecting accidental uncompressed pubkeys in witnesses)
* Determine "solvability" (would we be able to sign for this ignoring the fact that we may be missing some private keys).
The last item (solvability) is mostly unrelated and only rarely needed (there is just one instance, inside the wallet's coin control logic). This PR changes that instance to use the separate `IsSolvable` function, and stop `IsMine` from distinguishing between solvable and unsolvable.
As an extra, this also simplifies the `IsMine` logic and adds some extra checks (which wouldn't be hit unless someone adds already invalid scripts to their wallet).

80b4910f7d wallet: Use shared pointer to retain wallet instance (João Barbosa)
Pull request description:
Currently there are 3 places where it makes sense to retain a wallet shared pointer:
- `vpwallets`;
- `interfaces::Wallet` interface instance - used by the UI;
- wallet RPC functions - given by `GetWalletForJSONRPCRequest`.
The way it is now it is possible to have, for instance, listunspent RPC and in parallel unload the wallet (once #13111 is merged) without blocking. Once the RPC finishes, the shared pointer will release the wallet.
It is also possible to get all existing wallets without blocking because the caller keeps a local list of shared pointers.
This is mostly relevant for wallet unloading.
This PR replaces #11402.

This presumably slows down rescan, which uses a `CTransaction` and its `GetHash`, but never uses the `GetWitnessHash`. The slow down is proportional to the number of witness transactions in the rescan window. I.e. early in the chain there should be no measurable slow down. Later in the chain, there should be a slow down, but acceptable given the speedups in the modules mentioned above.

Pass an error message back from CWallet::Verify(), and call
InitError/InitWarning from WalletInit::Verify().
This means that we can call CWallet::Verify() independently from
WalletInit and not have InitErrors printed to stdout. It also means that
the error can be reported to the user if dynamic wallet load fails.
This allows a single wallet to be verified. Prior to this commit, all
wallets were verified together by the WalletInit::Verify() function at
start-up.
Individual wallet verification will be done when loading wallets
dynamically at runtime.
WalletInit::Start calls postInitProcess() for each wallet. Previously
each call to postInitProcess() would attempt to schedule wallet
background flushing.
Just start wallet background flushing once from WalletInit::Start().

Additionally `-upgradewallet` can now be used to upgrade a wallet from non-HD to HD. When it is used for such an upgrade, the keypool will be regenerated.

Bump the wallet version to indicate support for the pre split keypool.
Also prevents any wallets from upgrading to versions between HD_SPLIT
and PRE_SPLIT_KEYPOOL.
After upgrading to HD chain split, we want to continue to use keys
from the old keypool. To do this, before we generate any new keys after
upgrading, we mark all of the keypool entries as being pre-chain
split and move them to a separate pre chain split keypool. Keys are
fetched from that keypool until it is emptied. Only then are the new
internal and external keypools used.
Changes the maximum upgradewallet version to the latest wallet version
number, 159900. Non-HD wallets will be upgraded to use HD derivation.
Non HD chain split wallets will be upgraded to HD chain split.
If a non-HD wallet is upgraded to HD, the keypool will be entirely
regenerated.
Since upgradewallet is effectively run during a first run, all of the
first run initial setup stuff is combined with the upgrade to HD

both less clear for clients (as there are no guarantees about a
flush having actually happened prior to the call), and reults in

timer-based flushing.

Add label API to wallet RPC.
This is one step towards #3816 ("Remove bolt-on account system") although it doesn't
actually remove anything yet.
These initially mirror the account functions, with the following differences:
- These functions aren't DEPRECATED in the help
- Help mentions 'label' instead of accounts. In the language used, labels are
associated with addresses, instead of addresses associated with labels. (unlike
with accounts.)
- Labels have no balance
- No balances in `listlabels`
- `listlabels` has no minconf or watchonly argument
- Like in the GUI, labels can be set on any address, not just receiving addreses
- Unlike accounts, labels can be deleted.
Being unable to delete them is a common annoyance (see #1231).
Currently only by reassigning all addresses using `setlabel`, but an explicit
call `deletelabel` which assigns all address to the default label may make
sense.
Thanks to Pierre Rochard for test fixes.

>
> The enum classes ("new enums", "strong enums") address three problems with traditional C++ enumerations:
>
> * conventional enums implicitly convert to int, causing errors when someone does not want an enumeration to act as an integer.
> * conventional enums export their enumerators to the surrounding scope, causing name clashes.
> * the underlying type of an enum cannot be specified, causing confusion, compatibility problems, and makes forward declaration impossible.
>
> The new enums are "enum class" because they combine aspects of traditional enumerations (names values) with aspects of classes (scoped members and absence of conversions).

2fb9c1e shuffle selected coins before transaction finalization (Gregory Sanders)
Pull request description:
Currently inputs are ordered based on COutPoint ordering, which while doesn't leak additional internal wallet state, likely further fingerprints the wallet as a Core wallet to observers.
Note: This slightly changed behavior of `fundrawtransaction` in that the newly-appended inputs will now be shuffled rather than in outpoint-order. This does not break API compatibility.
Simple shuffling of the coins being returned will hopefully allow the wallet to blend in a bit more, in lieu of additional data to find what other wallets are doing, or another standard, ala @gmaxwell's suggested of ordering via scriptPubKey.

Rename account to label where appropriate
This change only updates strings and adds RPC aliases, but should simplify the implementation of address labels in https://github.com/bitcoin/bitcoin/pull/7729, by getting renaming out of the way and letting that change focus on semantics.
The difference between accounts and labels is that labels apply only to addresses, while accounts apply to both addresses and transactions (transactions have "from" and "to" accounts). The code associating accounts with transactions is clumsy and unreliable so we would like get rid of it.

Unfortunately I messed up my repo while trying to squash #12593 so I created a PR with just the correct fixes.

This change only updates strings and adds RPC aliases, but should simplify the
implementation of address labels in
https://github.com/bitcoin/bitcoin/pull/7729, by getting renaming out of the
way and letting it focus on semantics.
The difference between accounts and labels is that labels apply only to
addresses, while accounts apply to both addresses and transactions
(transactions have "from" and "to" accounts). The code associating accounts
with transactions is clumsy and unreliable so we would like get rid of it.
We don't want to use BnB when there are preset inputs because there
is some weirdness with making that work with using the KnapsackSolver
as the fallback. Currently we say that we haven't used bnb when
there are preset inputs, but we don't actually disable BnB. This fixes
that.

Pull request description:
This is an implementation of the [Branch and Bound coin selection algorithm written by Murch](http://murch.one/wp-content/uploads/2016/11/erhardt2016coinselection.pdf) (@xekyo). I have it set so this algorithm will run first and if it fails, it will fall back to the current coin selection algorithm. The coin selection algorithms and tests have been refactored to separate files instead of having them all in wallet.cpp.
I have added some tests for the new algorithm and a test for all of coin selection in general. However, more tests may be needed, but I will need help with coming up with more test cases.
This PR uses some code borrowed from #10360 to use effective values when selecting coins.

b4bc32a451 [wallet] Get rid of CWalletTx default constructor (Russell Yanofsky)
a128bdc9e1 [wallet] Construct CWalletTx objects in CommitTransaction (Russell Yanofsky)
Pull request description:
Two commits:
- `Construct CWalletTx objects in CommitTransaction` moves a bunch of CWalletTx initialization into CWallet::CommitTransaction to dedup some code and avoid future inconsistencies in how wallet transactions are created.
- `Get rid of CWalletTx default constructor` does what is described and eliminates the possibility of empty transaction entries being inadvertently created by mapWallet[hash] accesses.
Both of these changes were originally part of #9381
